HOUSE AND RUNNING TRAP.

SPECIFICATION forming part of Letters Patent No. 747,005, dated December 3- Application filed July 15, 1902. Serial No. 115.628. (No model.)

To all whom it may concern:

Be it known that I, HENRY SIEBEN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of 5 Missouri, have invented certain new and useful Improvements in House and Running Traps, of which the following is a specification.

This invention relates to back'water house and running traps, and has for its object to produce a device of this character which reliably prevents sewer-water from hacking into the house-pipes and which can be easily and quickly cleaned.

With this object and others in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is a side View of the trap. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a section taken on the line III III of Fig. 2.

In the said drawings, 1 designates an obtuse-angle shaped pipe so arranged that its major portion shall slope downwardly and provided near its upper end, where it connects with the house-pipe, (not shown,) with the usual air-vent 2. This pipe constitutes the trap proper by having its lower end upturned, as at 3, and said end is diametrically increased to form an internal shoulder 4.

5 designates the pipe member of the trap, which connects with the sewer, and is provided with a depending tubular arm 6, having its lower end flanged, as at 7, and engaging the grooved inner side of a fiber or other washer 8, capable of withstanding melt ed lead, as at 9, and forming a water-tight joint with shoulder 4:, on which it rests, without the necessity of calking, such Work being diflicult of perfect accomplishment be cause the trap is almost invariably close to a wall.

Myimproved construction above described not only provides a perfectly tightjoint, but it also leaves the passage perfectly clear and smooth, whereas in the old type of joint lumps of lead projecting into the passage are of frequent occurrence and offer obstructions to the free passage of contents foreign to the water.

At the outer angle of pipe 5 is an opening 10, whereby access is had to the trap for cleaning purposes when the cover 11 is removed, and hinged to and depending from said cover is a flap-valve 12, the same being adapted by gravity to prevent baekfiow of water through pipe 5 by covering opening 13 of an obliquely-arranged valve-seat 14:. This valve-seat is fitted at its upper end in groove 15 in the cover and at its sides and lower edge in groove 16 of pipe 5, and to prevent its withdrawal with the cover or its accidental displacement when the cover is removed and also to clamp it tightly in place it is provided with a bolt extension 17, projecting through an opening in the pipe and engaged by a clamping-nut 18.

In operation the water from the housepipes passes through the trap and raises or opens the flap-valve, the latter resuming its origi nal position after such flow of water ceases. The foul air from the house side escapes through vent 2 and in the sewer is excluded from the house by the water standing in the trap.

By removing cover 11 access is had to the trap and the pipe portion 5 thereof for cleaning or other purposes.

From the above description it will be apparent that I have produced a house and running trap which possesses the feature of advantage mentioned as desirable and which can be quickly and easily installed. 7

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

In a house and running trap, the combination of two members connected together and one to the house-pipe, and the other to the sewer, the last-named member having an' In testimony whereof I affix my signature in the presence of two witnesses.
